BARREL-FILLER.

SPECIFICATION forming part of Letters Patent No. 388,899, datedSeptember 4, 1888.

Application filed August 1, 1887.

To @255 whom it may concern..-

Be it known that I, LEWIS MILLER, a citizen of the United States,residing at 011 City, in the county of Venango and State ofPennsylvania, have invented a new and useful Improvement inBarrel-Fillers, of which the following is a specification.

This invention has for its object to provide means whereby the supply ofliquid will be antomatica ly and effectively stopped when the barril orother reoeptahle becomes filled or contains a certain predeterminedquantity.

To this end the invention consists in providing a stop cock or faucetol'any desirable shape or size with aspring-plug, a trigger forretaining the plug in opposition to its spring in open position, aspring hamlncr for operating the trigger, a lever for retaining thehammer in set position, and a releasing mechanism consisting of meanswhereby the pressure of the outrushing air is at the proper time broughtto bear upon and lift a diaphragm, which simultaneously communicates itsmovement to the end of the last-named lever, whereby the release of thehammer and tripping of the trigger follow in rapid succession, resultingin the almost simultaneous closing of the cock.

In order that my invention may be more fully understood, I will proceedto describe it with reference to the accompanying drawings, in whichFigure I is a perspective view of my apparatus, and Fig. II is avertical section thereof. Fig. III is a detail view showing the rubbercollar partly in section.

A represents the stop-cock having the cutoff D and nozzle 13. On theshell and cast integrally with it are the flanges P P, in which areformed the slots, project-ions, 8m, which support thelevers of thereleasing mechanism. The plug or cut-off block D has formed on it acylinder or drum, D, around which is wound a spiral spring, S, havingone end secured to the shell at s and the other inserted in one of aseries of perforations, 3 in the cylindrical drum and nutted on theinside. The cutoff block is further provided with a lever extending atright angles to its axis and preferably formed by inserting a bent rod,c, in the projection a, the latter being cast integrally with This rodct,being curved,as reprethe block.

Serial No. 245,867. (No model.)

sented, is adapted for prehension, and when turned down in a horizontalposition in oppo sition to the helical spring S is adapted to be engagedby the lower end of trigger b, which is l'ulerumed somewhat below itsmiddle in a slot in the flange P on pin 2;, passing through the sides ofsaid slot. The upper end of the trigger extends vertically through ahorizontal plane, in which swings an arm, a, pivoted on a stud or pin,0, inserted in the flange P, around which pin is coiled a spring, S, oneend of which is seen red by a screw passed through an eye formed thereonand inserted in the shell, as at s, the other engaging the swinging armby asmall upturned portion, 8". This swinging arm is adapted to be heldback in opposition to its spring some distance from the trigger-lever bya projection, c", on its end, which engages the L-shaped projection clon the ro clrlever d,

which is fulcrumed at d, and has its other end projecting forward anddownward,terminating at apoint above the vertical piston-rod e, which isadapted to lift it by an adjusting-screw, R. the end of which rests onthe square head e of said piston rod c. This lifting-rod works in atubular portion of a casing or housing, E, the lower part of which ishemispherical and secured by screws down onto a bracket, B, castintegrally with the nozzle and clamping between its periphery and thebracket aflexible diaphragm, e, to which the lifting-rod is secured bytwo nuts impinging on opposite sides thereof, the rod being insertedthrough the center of thediaphragm.

Cast in the nozzle is a small channel,k,which communicates with theunder side of the diaphragm by means of a recess, 7a. The other end ofthis channel communicates with the inside of the barrel when theapparatus is inserted. There is also cast in the nozzle a passage ofconsiderably larger capacity than the one is, and in this is inserted atube, H, movable vertically and adapted to be secured at any height by aclamp, G, held by a screw, g, working in a slot in said clamp.

The nozzle Bis made frusto-conical,with its lower portion cylindrical,or it may be made cylindrical and have a tapering rubber collarextending downabout half its length, as at B. The cylindrical portion isslightly cut away near its lower portion to allow the free anduninterrupted operation of a float, h, fulcrumed to an arm, h, on thetube H, and adapted to be lifted by the liquid to close the opening ofthe pipe H, which serves as the main outlet for air, and it also allowsfree access to the opening of the small air-passage.

M is the passage for oil or other liquids with which the vessel is to befilled, and it passes through the cock and down through the nozzle inthe usual way. The plug or cut-off block D has passage N through'itwhich is adapted to be closed by a quarter-revolution of the block D,caused by the spring S when the lever of said block is released fromengagement with trigger I).

z is a small portion of the nozzle not cut away, which serves as ashield for the tube and float. The two latter may freely pass downthrough the semicircular opening made by the piece 2.

In securing the handle to the shell I prefer to dovetail the ends of thebail and slide them down between the bevel-faces of two projecting lips,l 1, formed on the shell. I then insert a screw, 2, whiohsecures itagainst vertical or other movement. Acushion, p, is provided for thelever a of the cut-off block, against which it strikes when forcedaround. This is preferably done byinsertingin ahole in the projection pa small block of rubber, p. The stop-cock is screw-threaded at T forattachment to any pipe.

From the above description of the construction and arrangement of partsit will be readily seen that as the nozzle of the apparatus is insertedin the bung-hole an air-tight joint is made,and the apparatus being setto allow the liquid to flow in the displaced air must escape throughpipe H. "When, however, the liquid reaches a height such as to float theslopper h, the same closes the opening of the pipe H, the exit ofairisimmediately stopped, and a pressure developed within the vessel which issimultaneously communicated to the under side of the diaphragm. Thepiston rod rises, lifts the end of the rock-lever, thus releasing theswinging arm, which in turn strikes and rocks the trigger, whereby theblock-lever is disengaged and the cut-off block allowed to revolve bythe force of its spring, and thus cut off the flow of oil. The operationof all the parts is almost simultaneous and takes place immediately theoil reaches a certain height, so that a great quantity of oil otherwisewasted is saved by shutting off the supply at the proper time.

By raising or lowering the main outlet-pipe the float will be raisedsooner or later and the quantity of oillet in will be greater or less,as will be clearly seen.

I prefer to cast the shell with the flanges and nozzle in one piece; butI do not wish to limit myself to this method of forming the same, as itwill readily be seen that the shell may be cast in two pieces and joinedin any suitable manner by having the division come' in the flange P andthe two meeting faces secured together in any preferred manner.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In a barrel-tiller, the combination, with the shell A, having nozzleB, with bracket B, handle 0, and flanges P P, of spring plug D, springS, and lever a a, trigger b, swinging arm 0, operated by spring S, leverd,engaging with lever c,lifting-rod e',secured to diaphragm 0, housingE, said nozzle having air-passage is, leading to said diaphragm, andverticallyadjustable tube H, all arranged as shown and described.

2. The combination, with an automatic stopcock adapted to be set inoperation by airpressure on a diaphragm, of a nozzle for insertion in abung-hole, a vertically-movable tube for escape of air, a smallerchannel through which air-pressure is communicated to the diaphragm whenthe outlet is closed,

and a clamp, G, for holding the outlet-tube at a higher or lowerposition, for the purpose set forth.

3. The combination,with an automatic stop,

cock adapted to be set in operation by airpressure on a diaphragm, of anozzle for insertion in a bung-hole having an air-outlet tube verticallymovable therein and a channel through which air-pressure is communicatedto the diaphragm when the outlet is closed, for the purpose set forth.

4. The combination,with an automatic barrel-filler, substantially asdescribed, having a nozzle for filling a bung-hole, of averticallyadjustable tube making air-tight connection with the nozzleand having a projection, It, on which is fulcrumed a float, h, adaptedto close the said tube, whereby escape of air from the vessel isprevented.
